A seizure occurs when the message delivery system becomes unbalanced. Under normal circumstances, the neurotransmitter GABA does its part to make sure the system stays in synch by triggering signals in the form of charged particles (A). It causes a large concentration of negatively charged chloride particles (Cl-) to enter the receiving neuron. This tells the neuron to not pass on the message. When there is not enough GABA a person can have a seizure because receiving neurons can be flooded with signals that say "pass on this message." The "go" messages are triggered by a different type of neurotransmitter that promotes message transfer (B). the charged signals they set off are positive. This time, more positively charged sodium particles (Na+) enter the neuron, which tells the receiving neuron to pass on the message. (Epilepsy and GABA)

Epilepsy Overview
Epilepsy is a neurological disorder that occasionally produces brief disturbances in the normal electrical functions of the brain and is characterized by a tendency for people to have recurrent seizures. Normal brain function is made possible by millions of electrical charges passing between nerve cells in the brain to the entire body. When someone has epilepsy the normal pattern is interrupted by intense bursts of electrical energy that affect people's consciousness and bodily movements for a short period of time. For about seventy percent of people, there is no known cause of epilepsy. For everyone else the cause may be anything that could interupt the brains delicate electrical system; possibilities range from head injuries to birth. There are different types of epilepsy and seizures. Epilepsy drugs are prescribed to control seizures, and rarely surgery is necessary if medications are ineffective(WebMD).
